Morphology General Floats
Floats terminal on short lateral slightly inflated villous branches, verticillate, 4(–5–6)–9, fusiform or narrowly cylindrical to ovoid or ellipsoid, 0.3–2.5 cm. long, bearing in the distal half a number of leaf-segments.

Morphology Reproductive morphology Flowers Corolla
Corolla mauve or pale purple with a yellow blotch on the palate or wholly white, 10–15 mm. long; upper lip oblong, 3–4 times as long as the upper calyx-lobe, ± auriculate at the base, deeply divided into 2 parallel lobes; lower lip reniform, 7–10 mm. wide, apex ± emarginate; palate with a narrow raised ± crenulate rim; spur cylindrical or botuliform, 2–3 times as long as the lower lip, 8–10 mm. long, 2.5–3.5 mm. thick; corolla of cleistogamous flowers obsolete or nearly so.

Morphology Reproductive morphology Fruits
Capsule ellipsoid, 2.5–3.5 mm. long, circumscissile.
Morphology Reproductive morphology Seeds
